The rate of electron transfer, between dissolved decamethylferrocene molecules and an oxocuprate high temperature superconductor [Tl 1223] electrode, represented in impedance spectroscopy by an electrical resistance term RCT, is shown to be measurable (RCT tending to dip around the superconducting transition temperature), so opening up the prospect of a new, controllably variable, probe of superconductivity.
